This European Standard was approved by CENELEC on 2007-05-01. CENELEC members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

Foreword This European Standard was prepared by the Technical Committee CENELEC TC 40XB, Resistors. The text of the draft was submitted to the Unique Acceptance Procedure and was approved by CENELEC as EN 140401-803 on 2007-05-01. This European Standard supersedes EN 140401-803:2002 + A1:2003. Preceding documents on the subject covered by this specification have been – CECC 40 401-803:1997, only on resistors without established reliability, now version A: – CECC 40 401-005:1990; 1991; 1992, only on resistors with established reliability, now version E: – CECC 40 401-001:1988; 1990.
Compared to the superseded standard, the following changes have been implemented: – modification of the title; – introduction of a test on the resistance to electrostatic discharge in 1.6 and Annex A; – introduction of description and test methods for lead-free soldering in 1.8, 1.10.3 and Annex A; – introduction of the code letters for temperature coefficient as given in EN 60062; – revision of the ordering information in 1.9.4; – revised information on pulse load capability in 1.10.6; – revised information on resistance value drift in 1.10.7; – revised information on current noise in 1.10.9; – adoption of the IECQ rules of procedure, QC 001002-3; – revision of the sample quantities and the sequence of tests in Annex A; – editorial revision. The following dates were fixed: – latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement
(dop)
2008-05-01 – latest date by which the national standards conflicting
with the EN have to be withdrawn
